Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-130A

Condition




The engine control module (ECM) measures the air mass through the intake manifold using a sensor. The diagnostic trouble code (DTC) is stored if the engine control module (ECM) detects that the sensor value deviates too much from a calculated value.
The diagnostic trouble code (DTC) can be diagnosed when:
- The engine is at operating temperature
- Engine speed (RPM) is approximately 700-5500 rpm
- Throttle angle is approximately 2-60°.

Substitute value
- A value calculated from engine speed (RPM) and pressure in the intake manifold is used.

Possible source
- Contact resistance in the connector
- Damaged fresh air intake hose
- Damaged mass air flow (MAF) sensor.

Fault symptom[s]
- Malfunction indicator lamp (MIL) lit
- Jerky operation.
